Epson M2120 Adjustment Program -
The Epson M2120 Adjustment Program (also known as the AdjProg or Resetter) is a specialized maintenance utility used to service Epson monochrome EcoTank printers. It is primarily utilized when a printer displays a "Service Required" error, indicating that the internal waste ink pads have reached their theoretical limit. Primary Functions
The program allows users to perform technical adjustments that are typically restricted to authorized service centers:
Waste Ink Pad Counter Reset: Clears the internal counter so the printer can resume operation after the "Service Required" message appears.
Print Head Maintenance: Includes "Deep Cleaning" cycles and "Head ID" settings to ensure optimal print quality.
Mechanical Adjustments: Allows for "Top Margin" and "Bi-Directional (Bi-D)" alignment to fix overlapping or crooked text.
EEPROM Operations: Can be used to back up or initialize the printer's internal settings during a motherboard replacement. How to Use the Adjustment Program To utilize this tool, you generally follow these steps: epson m2120 adjustment program
Preparation: Connect your Epson M2120 to a computer via a USB cable (Wi-Fi resets are often unreliable) and ensure the printer is powered on.

Adjustment Mode: Click on "Particular Adjustment Mode" to see the full list of maintenance options.
Resetting: For ink pad issues, select "Waste ink pad counter". Check the boxes for the counters (e.g., Main pad counter), click "Check" to see current levels, and then "Initialize" to reset them to zero.
Restart: Once the program confirms the reset, turn the printer off and back on to clear the error. Important Considerations The Epson M2120 Adjustment Program (also known as
Hardware Maintenance: Simply resetting the software counter does not remove the physical ink from the pads. To avoid leaks or internal damage, you should physically clean or replace the waste ink pads or install an external waste ink tank.
Software Sources: Many versions of this program found online are third-party tools. Common alternatives include the WIC Reset Utility, which is often easier to use but may require a one-time purchase "key" for the reset function. Reset Epson M2120 Wicreset Key
⚠️ Crucial Warnings Before You Begin
Before you download and run the program, you must understand the physical reality of the reset.
Resetting the counter does not physically clean the ink pads. The software simply tells the printer, "The pads are empty again, keep printing." If your pads are genuinely saturated with ink, resetting the counter will allow the printer to print, but ink will eventually overflow, leaking out of the bottom of the printer and damaging your desk or electronics.
Best Practice: If you have used your M2120 for several years and see this error, it is highly recommended to physically replace or clean the waste ink pads (or install an external waste ink tank) before performing the software reset. ⚠️ Crucial Warnings Before You Begin Before you

If you have addressed the physical waste ink issue and are ready to proceed with the software reset, follow these steps carefully.
Why Do You Need It? The "Service Required" Error
The most frequent reason users search for this tool is the dreaded "Service Required" or "A printer’s ink pads are at the end of their service life" error. On the M2120 display, you might see error codes like: 0x9A, 0x9B, or 0x9C.
Here is what is actually happening: The Epson M2120, like all inkjet printers, uses a spongy "waste ink pad" inside the chassis to absorb ink purged during cleaning cycles. Epson programs a counter into the firmware that tracks estimated pad saturation. At a predetermined threshold (typically around 15,000–20,000 pages), the printer hard-locks itself.
Epson’s official solution: Replace the entire waste ink pad assembly (costly and labor-intensive) or send the printer to a depot. The technician’s solution: Use the Adjustment Program to reset the counter to zero. (Note: Only do this if the pad is not physically overflowing).
